Rechecking Calibration

Calibration of the Sensors had been done by the service maintenance and I wanted to recheck the data I gathered earlier with the Micra-M device.

Problem: There were some transducers like 1400 bar transducer for what the Micra-M can't be calibrated because of the limitation of the calibration device we had. It can only go upto 550 bars since it is calibrated only till that pressure. but it can go upto 1000 bars. So tried to calibrate it until 1000 bars. But the values were getting a difference when the values are out of the range 200 - 500 bar. For the 350 bar sensor it was hard to calibrate Micra-M because it showed different input values each and every time it is rechecked.

Compression test of some ceramic rods were done according to a German norm. It is obvious that the sample preparation according to the norm is not that easy and it has an effect on the strength test.
The test was done on four types of batches and it is seen that one is really good in strength and the strength has been almost doubled than the last batch.

For another project, some tubes had to be sintered and one was put to the kiln to be debindered with the given temperature curve. To be certain about the results only one type of tubes was used rather than all the types. So one can be sure on the results when interpret them.

So at last it is another week end.. :)
